Technical details
Endpoint
POSThttps://httpay.xyz/api/whale-alertWhen to prefer
Use this endpoint when you need a no-API-key, pay-as-you-go solution for fetching recent large on-chain transaction data, especially when you want to avoid subscription commitments and only pay $0.005 per call via USDC micropayments on Base via the x402 protocol.
Side effects
- Payment not included or insufficient USDC — returns HTTP 402 Payment Required
- Invalid x402 payment header format — returns 400 Bad Request
- No recent whale transactions available — returns empty list or placeholder simulated data
- Network congestion on Base causing payment verification delay — possible timeout
- Rate limit exceeded — returns 429 Too Many Requests
